DESCRIPTION OF EMBODIMENTS
In order to clarify the purpose, technical solutions, and
advantages of the embodiments of the present disclosure, the
technical solutions in the embodiments of the present disclosure
will be described in the following with reference to the
accompanying drawings. It should be clear that the described
embodiments are merely part of the embodiments of the present
disclosure rather than all of the embodiments. All other
embodiments obtained by those skilled in the art without paying
creative labor shall fall into the protection scope of the present
disclosure.
The terms used in the embodiments of the present disclosure are
merely for the purpose of describing particular embodiments but not
intended to limit the present disclosure. Unless otherwise noted in
the context, the singular form expressions "a", "an", "the" and
"said" used in the embodiments and appended claims of the present
disclosure are also intended to represent plural form expressions
thereof.
It should be understood that, the term "and/or" is used in the
present disclosure merely to describe relations between associated
objects, and thus includes three types of relations. That is, A
and/or B can represent: (a) A exists alone; (b) A and B exist at
the same time; or (c) B exists alone. In addition, the character
"/" generally indicates "or".
It should be understood that although terms "first", "second",
"third" etc. are used to describe clock signal lines, power signal
lines, gate driving transistors, gate driving capacitors, virtual
driving transistors, virtual driving capacitors, clock signal input
terminals, and power signal input terminals, they shall not be
interpreted as limiting the specific clock signal lines, power
signal lines, gate driving transistors, gate driving capacitors,
virtual driving transistors, virtual driving capacitors, clock
signal input terminals, and power signal input terminals. These
terms are merely used to distinguish the clock signal lines, power
signal lines, gate driving transistors, gate driving capacitors,
virtual driving transistors, virtual driving capacitors, clock
signal input terminals and power signal input terminals from one
another. For example, without departing from the scope of the
embodiments of the present disclosure, a first clock signal line, a
first power signal line, a first gate driving transistor, a first
gate driving capacitor, a first virtual driving transistor, a first
virtual driving capacitor, a first clock signal input terminal and
a first power signal input terminal may also be referred to as a
second clock signal line, a second power signal line, a second gate
driving transistor, a second gate driving capacitor, a second
virtual driving transistor, a second virtual driving capacitor, a
second clock signal input terminal and second power signal input
terminal, respectively. Similarly, a second clock signal line, a
second power signal line, a second gate driving transistor, a
second gate driving capacitor, a second virtual driving transistor,
a second virtual driving capacitor, a second clock signal input
terminal, and a second power signal input terminal may also be
referred to as a first clock signal line, a first power signal
line, a first gate driving transistor, a first gate driving
capacitor, a first virtual driving transistor, a first virtual
driving capacitor, a first clock signal input terminal, and a first
power signal input terminal, respectively.
FIG. 1A and FIG. 1B are designs of gate driving units commonly used
in a rounded angle region. As shown in FIG. 1A, a plurality of gate
driving units SL is arranged in a non-rounded angle region, and a
first gap JL is formed between two adjacent gate driving units SL
in the non-rounded angle region. A plurality of gate driving units
SR is arranged in a rounded angle region, and a second gap JR is
formed between two adjacent gate driving units SR in the rounded
angle region. As can be seen from FIG. 1A, since the number of gate
driving units required for per unit length in the rounded angle
region is smaller than the number of gate driving units required
for per unit length in the non-rounded angle region, the second gap
JR is bigger than the first gap JL. That is, the number of gate
driving units per unit area in the rounded angle region is smaller
than the number of gate driving units per unit area in the
non-rounded angle region, i.e., there are more blank regions in the
rounded angle region. In this case, the rounded angle region and
the non-rounded angle region may be unevenly etched, thereby
affecting the encapsulation effect. In order to fill the blank
region, it is conventional to make certain changes to the gate
driving unit, for example changing it into a trapezoidal shape, an
irregular quadrilateral or the like, which is different from the
gate driving unit in the non-rounded angle region. As shown in FIG.
1B, a plurality of gate driving units SL is arranged in the
non-rounded angle region, and each of the plurality of gate driving
units SL in the non-rounded angle region is formed as a rectangular
shape. A plurality of gate driving units SR is arranged in the
rounded angle region, and each of the plurality of gate driving
units SR in the rounded angle region is formed as a non-rectangular
shape and has a larger area than the gate driving unit SL in the
non-rounded angle region. With such a design, although the blank
regions may keep consistent, the gate driving units have a
decreased uniformity, which affects the internal etching of the
gate driving units as well as the subsequent encapsulation and thus
has an influence on the gate driving unit device and even on the
display effect.
An embodiment of the present disclosure provides a display panel
100. As shown in FIG. 2 and FIG. 3, the display panel 100 has a
display region 101 and a peripheral region 102. The display panel
100 includes a plurality of gate lines Gate, a plurality of data
lines Data, a plurality of pixel units P, a first clock signal line
CL1, a second clock signal line CL2, a first power signal line V1,
and a second power signal line V2. Herein, the plurality of data
lines Data is insulated from and intersects with the plurality of
gate lines Gate.
With further reference to FIG. 2 and FIG. 3, the display panel 100
further includes a plurality of gate driving units S and a
plurality of virtual driving units D. Each gate driving unit S has
a first clock signal input terminal CKQ1, a second clock signal
input terminal CKQ2, and an output terminal Qout. The output
terminal Qout of the gate driving unit S is electrically connected
to the gate line Gate, the first clock signal input terminal CKQ1
of the gate driving unit S is electrically connected to the first
clock signal line CL1, and the second clock signal input terminal
CKQ2 of the gate driving unit S is electrically connected to the
second clock signal line CL2. It should be noted that when the
first clock signal input terminal CKQ1 of one stage of gate driving
unit S is electrically connected to the first clock signal line CL1
and the second clock signal input terminal CKQ2 of this stage of
gate driving unit S is electrically connected to the second clock
signal line CL2, the first clock signal input terminal CKQ1 of a
next stage of gate driving unit S is electrically connected to the
second clock signal line CL2 and the second clock signal input
terminal CKQ2 of the next stage of gate driving unit S is
electrically connected to the first clock signal line CL1. That is,
the respective first clock signal input terminals CKQ1 of the
plurality of gate driving units are alternately electrically
connected to the first clock signal line CL1 and the second clock
signal line CL2, and the respective second clock signal input
terminals CKQ2 of the plurality of gate driving units are
alternately electrically connected to the first clock signal line
CL1 and the second clock signal line CL2.
With further reference to FIG. 2 and FIG. 3, each virtual driving
unit D has a first clock signal input terminal CKD1, a second clock
signal input terminal CKD2, and an output terminal Dout. The output
terminal Dout of the virtual driving unit D is insulated from the
gate line Gate, and the first clock signal input terminal CKD1 and
the second clock signal input terminal CKD2 of the virtual driving
unit D are both insulated from the first clock signal line CL1 and
the second clock signal line CL2. That is, although the virtual
driving unit D has a same or similar design as the gate driving
unit S, the virtual driving unit D is not connected to the gate
line Gate, the first clock signal line CL1 or the second clock
signal line CL2. That is, unlike the gate driving unit S, the
virtual driving unit D does not have the function of driving the
gate line Gate and performing signal shift. The peripheral region
102 includes at least one rounded angle region, and at least one
virtual driving unit D is arranged in the rounded angle region and
located between two gate driving units S.
In an embodiment, the first power signal line V1 can input a
high-level signal, and the second power signal line V2 can input a
low-level signal. The virtual driving unit D can have exactly the
same design as the gate driving unit S, or a ratio of an area of
the virtual driving unit D to an area of the gate driving unit S
can be within a range of 0.99:1 to 1:0.99.
For the display panel 100 provided by this embodiment of the
present disclosure, at least one virtual driving unit D, which is
the same as or similar to the gate driving unit S, is arranged
between the gate driving units S in the rounded angle region, such
that a position without the gate driving unit S in the rounded
angle region is filled, and thus the problem of uneven etching in
the rounded angle region can be solved and the reliability and
yield of the display panel 100 can be improved.
In an embodiment, as shown in FIG. 4, an input terminal Qin of the
gate driving unit S is electrically connected to the output
terminal Qout of a previous stage of gate driving unit S, and a
virtual signal input terminal Din of the virtual driving unit D is
electrically connected to the first power signal line V1. The
virtual signal input terminal Din of the virtual driving unit D is
electrically connected to the first power signal line V1, so as to
increase the electrostatic discharge path. Thus, the virtual
driving unit D can be used as an electrostatic discharge unit,
further increasing the reliability of the display panel 100.
It should be noted that, in other embodiments of the present
disclosure, for example, the input terminal Qin of the gate driving
unit S is electrically connected to the output terminal Qout of a
previous stage of gate driving unit S, and the virtual signal input
terminal Din of the virtual driving unit D is floating. That is,
the virtual signal input terminal Din of the virtual driving unit D
is not electrically connected to any signal line and does not
access any signal. Floating the virtual signal input terminal Din
of the virtual driving unit D can simplify the trace design and
avoid an impact of a cross-bridge design on other signal lines.
An embodiment of the present disclosure further provides a display
panel. With reference to FIG. 5 and FIG. 6, the gate driving unit S
includes a plurality of gate driving transistors Q1 to Q8, and the
virtual driving unit D includes a plurality of virtual driving
transistors D1 to D8. The number (eight) of gate driving
transistors in the gate driving unit S is equal to the number
(eight) of virtual driving transistors in the virtual driving unit
D. It should be noted that FIG. 5 and FIG. 6 merely illustrate one
circuit design of a gate driving unit and a virtual driving unit.
In other embodiments of the present disclosure, it is also possible
that the gate driving unit includes seven, nine, ten, or other
number of gate driving transistors, as long as the number of
virtual driving transistors in the virtual driving unit is equal to
the number of gate driving transistors in the gate driving
unit.
According to the display panel provided by this embodiment of the
present disclosure, since the number of virtual driving transistors
of the virtual driving unit D is equal to the number of gate
driving transistors of the gate driving unit S, the virtual driving
unit D can be designed to be consistent with the gate driving unit
S to a maximum extent, i.e., the circuit designs of the two can be
basically the same. This can achieve design uniformity for per unit
area in the rounded angle region and per unit area in the
non-rounded angle region, and thus the problem of uneven etching
can be solved and the encapsulation reliability of the yield of the
display panel can be improved.
An embodiment of the present disclosure further provides a display
panel, as shown in FIG. 5 and FIG. 7, or FIG. 5 and FIG. 8. As
shown in FIG. 5 and FIG. 7, the gate driving unit S includes a
plurality of gate driving transistors Q1 to Q8, and the virtual
driving unit D includes a plurality of virtual driving transistors
D1 to D7. The number (eight) of gate driving transistors in one
gate driving unit S is larger than the number (seven) of virtual
driving transistors in one virtual driving unit D. As shown in FIG.
5 and FIG. 8, the gate driving unit S includes a plurality of gate
driving transistors Q1 to Q8, and the virtual driving unit D
includes a plurality of virtual driving transistors D1 to D6. The
number (eight) of gate driving transistors in one gate driving unit
S is larger than the number (six) of virtual driving transistors in
one virtual driving unit D. It should be noted that FIG. 5 merely
illustrates one circuit design of the gate driving unit. In other
embodiments of the present disclosure, it is also possible that the
gate driving unit includes seven, nine, ten, or other number of
gate driving transistors, as long as the number of virtual driving
transistors in the virtual driving unit is smaller than the number
of gate driving transistors in the gate driving unit.
According to the display panel provided by this embodiment of the
present disclosure, since the number of virtual driving transistors
in the virtual driving unit D is slightly smaller than the number
of gate driving transistors in the gate driving unit S, the
transistor close to the signal line can be removed while
maintaining the similarity between the virtual driving unit D and
the gate driving unit S, i.e., maintaining the similarity between
circuit designs. In this way, the circuit load and interference can
be reduced. The display panel provided by this embodiment of the
present disclosure can not only maintain the similarity of design
per unit area between the rounded angle region and the non-rounded
angle region, solve the problem of uneven etching and improve the
encapsulation reliability of the display panel, but also reduce the
energy consumption and interference of the display panel, improve
the yield of the display panel and improve the user experience.

the second clock signal input terminal CKD2, and the virtual signal

simplified and the panel complexity can be reduced.
As shown in FIG. 2, FIG. 5 and FIG. 8, an embodiment of the present

a wiring manner of the virtual driving unit D shown in FIG. 7, the

input terminal CKD2, and the virtual signal input terminal Din of
the virtual driving unit D are all floating. The third power signal
input terminal VD3 of the virtual driving unit is electrically
connected to the second power signal line V2. It should be noted
that in other embodiments of the present disclosure, the third
power signal input terminal VD3 of the virtual driving unit may
also be floating or electrically connected to the first power
signal line V1. It should be noted that FIG. 15 merely illustrates
an exemplary wiring manner and connection manner of the virtual
driving unit D. In other embodiments of the present disclosure, the
first clock signal input terminal CKD1, the second clock signal
input terminal CKD2, and the virtual signal input terminal Din of
the virtual driving unit D may also be electrically connected to

For the display panel 100 provided by this embodiment of the
present disclosure, the number of the transistors of the virtual
driving unit D is only two less than the number of the transistors
of the gate driving unit S (the virtual driving unit D does not
include a third gate driving transistor Q3 or a fifth gate driving
transistor Q5 existing in the gate driving unit S), so that the
arrangement of the internal devices in the virtual driving unit D
and the arrangement of the internal devices in the gate driving
unit S have high consistency. The third gate driving transistor Q3
closest to the second power signal line V2 in the gate driving unit
S is removed from the virtual driving unit D, and the fifth gate
driving transistor Q5 closest to the first power signal line V1 in
the gate driving unit S and having a dual-gate structure is removed
from the virtual driving unit D. In this way, the coupling effect
of the transistor with the second power signal line V2 and the
coupling effect of the transistor with the first power signal line
V1 can be reduced, thereby further improving the stability of the
panel and reducing the power consumption of the panel. In addition,
if the first clock signal input terminal CKD1, the second clock
signal input terminal CKD2, and the virtual signal input terminal
Din of the virtual driving unit D are connected to a fixed signal
(i.e., being electrically connected to the first power signal line
or the second power signal line), the electrostatic discharge path
of the display panel 100 is increased, thereby further improving
the reliability of the display panel 100. If the first clock signal
input terminal CKD1, the second clock signal input terminal CKD2,
and the virtual signal input terminal Din of the virtual driving
unit D are floating, the panel design can be simplified and the
panel complexity can be reduced.
